How to Fix / Troubleshooting
Safety: Unplug the appliance before inspection.
User-level checks:
- Observe whether the interior light turns on and off correctly when opening and closing the door (without starting a program).
- If the light behavior is inconsistent, a door sensing issue is likely.
Technician-level checks:
- Test the door sensing switch (often separate from the main interlock switches) for proper operation.
- Inspect the lamp holder and wiring for shorts or burned insulation.
- Check the control PCB area driving the lamp for damage.
- Replace the faulty switch, lamp assembly, or control PCB as indicated by tests.
Because door sensing is tied to safety interlocks, repairs should be done by a qualified technician.
